The "spin-only" magnetic moment [in units of Bohr magneton, `(mu_B)`] or `Ni^(2+)` in aqueous solution would be :
(At no. `Ni = 28`).

A

2.83

B

4.9

C

0

D

1.73

Text Solution

Verified by Experts

The correct Answer is:
A
`Ni^(2+)` in aqueous solution means `[Ni(H_(2)O)_(6)]^(2+)` . The electronic configuration of

Total number of unpaired electron `=2`
`:. `Spin only magnetic moment of `Ni^(2+)`
`=2 sqrt(2(2+2))= 2 sqrt(2) = 2.83 B.M.`
